Todoroki was walking down the hall to one of his classes, and in passing Nezu's office, he froze- hearing Aizawa's and Nezu's voice, along with yours. Curious, he stopped to listen for a moment. Perhaps he was being nosey, and it wasn't his business, but he couldn't help but be worried. And what he heard was definitely something to worry about- hearing how you didn't have anywhere to go for holiday leave, and he didn't like the idea of you staying at the dorms by yourself- it was Christmas, after all.
Before your final class, 1-A Hero training with Aizawa, Todoroki stopped you by your locker.
"Hey, I know I might be intruding, but I heard your conversation with Nezu earlier," He started, with his expression something softer than his normal deadpanned look.
"Why don't you stay with me instead? We have the room. Besides, my family wants to meet you- and don't worry about my father, I won't let him give you any trouble."
